| Mar 26, 2025 | Steamworks Brewpub – Uber Room, 375 Water St., Vancouver, BC | TAC BC Vancouver TAC Talk Join the TAC BC Chapter for the upcoming presentation event on Design and Construction of Sydney Metro Wester – Western Tunnelling Package featuring speaker Brendan Henry (P.Eng BC, C.Eng MICE), Practice Leader for GHD Tunnels. Abstract: Design development of Tunnels in Sydney Metro West - Western Tunnelling package: This presentation explores the design and construction of mined rail yard tunnels, TBM running tunnels, and cross passages. It highlights key design challenges and showcases successfully completed works. Delegates will gain an understanding of the design and construction of the rail yard access tunnels with Roadheader in Sandstone and the complexity of the tunnelling around the portal location and the design and excavation of the running tunnels with twin double shield TBMs. About the speaker: Brendan has 30 years of experience on a wide range of tunnelling and heavy civil engineering projects as contractor and designer, working in UK, Singapore, Canada and for the last 14 years, Australia, arriving in 2008 as Engineering Manager for the TBM Tunnels on Airport Link with John Holland. Brendan has now been with GHD for 12 yrs, working on all phases of tunnel project delivery and most recently on pumped storage hydroelectric and water security projects. Registration Cost: $5 for members, $10 for non-members, includes one beverage and shared appetizers (paid at the door) Please RSVP your interest in attending to Alexander MacKinnon at alexander.mackinnon@wsp.com and Julian Arambarri at jarambarri@aldeaservices.com. | Payment will be processed on site. |
| Apr 17, 2025 | Lone Star Texas Grill - 930 Dixon Rd, Toronto, Ontario | TAC Ontario Chapter Event: The role of mechanized shaft sinking with VSM in inner-city applications Title: The role of mechanized shaft sinking with VSM in inner-city applications Presenter: Stefan Frey Product Manager VSM – Shaft Sinking Business Unit Utility Tunnelling Herrenknecht AG Abstract: Space on the surface is becoming increasingly scarce and expensive. Safe and economic construction of underground infrastructure in steadily increasing depths requires mechanized tunnelling and shaft sinking solutions. Shafts are needed for tunnelling operations, sewer systems, storage or for ventilation and rescue purposes in traffic tunnels. The Vertical Shaft Sinking technology (VSM) is a mechanized approach developed to overcome challenging mixed ground conditions with high groundwater tables, and safety or economic limits of conventional methods. Since 2004, far more than 100 circular shafts have been sunk with VSM, in depths of up to 115 meters and an inner shaft diameter range from 4.5 to 12 meters. The VSM is remote-controlled from the surface, thus, it is a completely unmanned sinking procedure without personnel required in the shaft during the sinking process. It meets the key requirements for shaft construction in inner cities: no groundwater lowering, maximum production accuracy and safety, and flexible arrangement of jobsite equipment. Due to the electrified operation of the overall VSM equipment with the possibility to be powered by the local grid, the CO2 footprint and noise emissions can be considerably reduced compared to conventional construction methods. When using prefabricated concrete segments, shaft sinking with VSM requires up to 40% less concrete for the shaft structure. This presentation will introduce the VSM technology, with international project references in urban infrastructure projects. About Stefan Frey: Stefan Frey was born in 1977 in Freudenstadt, Germany. After his degree in Mechanical Engineering he started working for Herrenknecht AG in 2007 as a Project Manager in the Business Unit Utility Tunnelling, in charge of worldwide Shaft Sinking and Utility Tunnelling projects. In 2016 he has become the Product Manager for Vertical Shaft Sinking Equipment (VSM). His focus is on the further development of mechanized shaft sinking and the evaluation of its applicability in international underground projects. | Registrater HERE! |
